Superman and his super-son Jon are back in the second volume by best-selling author Peter J. Tomasi!

With Jon becoming more and more powerful by the day, Superman's greatest foes are starting to take notice of the new super-kid on the block. When one of the most evil and ruthless of Superman's rogues' gallery comes for the Man of Steel's son, Clark must decide just how far he's willing to go to protect the ones he loves.
Superman and Jon Kent are transported to Dinosaur Island to find the last of the Losers! Then, after a quick trip to the county fair, Jon meets his match in Damian Wayne—and the Super Sons’ fathers soon put the two young heroes through their paces as a new crime-fighting team is forged!
